Does anyone use the stuff? If so what is the best brand? Also thinking of droping in a K&N filter replacement (not CAI don't have the cash) any thoughts?

 

1. Injector cleaner- I use BG Products (not Barry Grant)- their product is excellent and sold at most car dealers, etc. they have a web site and a distributor can tell you where to purchase.

2. I also run Marvel Mystery Oil to maintain fuel injector/system cleanliness (I use 1 oz per gallon for routine use or 16 oz per 12 gallons of fuel every 6 months). Since I started doing this in 1986, I have yet to have to replace an injector or get the fuel system cleaned on any FI vehicle that I have owned.

3. Air filters:
If you do an online search for “air filter test” there is a lot of very good information. IMHO, the CAI units are NOT WORTH THE $$! Unless you are talking about a system that was specifically designed for a specific application there are very little hp/tq gains actually achieved in a street use vehicle and there are very few docs that these mfg’s can produce that actually show an increase in hp/tq in the power-band range of a relatively stock street vehicle.

I would avoid oil impregnated filters. While they have their purpose in off-road applications, Ford/GM/Dodge all have “watch-out” bulletins where the oil has contaminated intake sensors.

If you look at the flow data, WIX HP filters flow 98+% of K&N and have a much smoother flow post filter plus excellent filtering, for a fraction of the price! The OE’s have an excellent air intake system the only issue that really exists is the plastic intake tube with it’s noise canceling design- that does reduce the intake efficiency a little but makes it very quiet!. You can use a WIX OEM HP replacement filter in the OEM plastic manifold box and either remove the plastic tube and replace it with a piece of pipe/hose, etc or remove the tube completely and replace the tube by building an air ram type intake into the air box manifold (where the pipe use to attach)- make sure ti terminates above the fan shroud to avoid water intake or fan induced pulsations.

 

This is like talkin whiskey. I avoid it but it's good once in a while. I've been using Lucas stuff for years and have always done well with that

 

The manuel says not to use any treatment. I use Lucas from time to time. Also it is a good idea to use a name brand gas. I usually fill up with Shell, BP,or Chevron. Finally stay away from the K& N filter with the 5.4. The stuff that you spray on the filter will cause you problems.

 

We don't have Chevron here, so every 3 months I run a big bottle, and a little bottle of Techron through with a full tank. (37 Gallon) I also ran it through after I got some really bad gas a few weeks ago.
